l The invention relates to door bumpers and has for one of its objects the construction of a sectional door bumper which may be readily clamped to an anchoring member and which has provision for receiving a' cushion for engaging a door. Another object is to so arrange the bumper that it maybe readilysecured to a like bumper for another door and thereby held more firmly in place. With these as well as other objects in view, the invention resides in the novel features of construction and combinations andarrangements of parts as more fullyhereinafter set forth.

The door bumper embodylng my invention ing only a portion of the door bumper applied is shown in the present instancefor use with a sliding door 1 of an airplane hangar, which door is mounted upon wheels or rollers 2 movable along the head 3 of the I-beam rail 4:. The airplane hangar has a plurality of these doors, each of which is movable along a track having a portion extending paralleland adjacent .to portions of the other tracks and there is a bumper for each door secured to and extending longitudinally of each of these track portions. I l Y The door bumper isv formed'of the complementary cooperating sections 5, each section having a body formed with a side wall 6 and front and rear end walls 7 and 8, respectively. The side wall 6 is formed at its lower end with the channel-shaped projection 9 and at its upper end with the arcuate portion 10. For reinforcing each section there is the web 11 which extends transversely from the inner edge of the rear wall and above, the arcuate portion 10. There are alsothe reinforcing 1929;- Serial No. 355,400.

webs 12 which extend transversely of the side wall 6 near its lower end and in registration with and in continuation of the lower ends of the front and rear side walls. Eachreinforcing web 11 terminates at a point adja' cent to butspaced from the projection 9' to form a recess '13 :for receiving the head 3 0i the rail l. Each projection 9is adapted'to engage the rail between the head '3 and the base 14 of the rail. The projections 9 of the cooperating sections, as well as therecesses 13 and the arcuate portions 10, are located to be opposite each other when these sections are clamped together and upon the -rail, the arouate portions with the upper portions of the rear wall 8 cooperating toform'a cavity or cup to receive the cushion 15for engaging the door, this cushionbeing preferably formed of rubber. 'To clamp the sections together and upon the rail which forms the anchoring member of the door bumper, I provide'the bolts 16 which extend transversely through the sidewallsd near their lower ends and above the rail 4 and'the nuts 17 threaded upon these bolts. Ii alsoprovide the'bolt-l8extend ing transversely through the reinforcingweb v11 above the arcuate portions 10 and the nut 19 threaded upon this bolt foriclamping the upper ends of the sections together and for clamping the cushion 15in place.

For limiting the-movement of I thef sections toward each other and at the same timeilrfeinforcing these sections; I f have provided 7 upon. each section the transverse inwardly.

' extendingrib 20 which connects itin'tothe' front and rear walls andii's" integral.- there? ;with*as'wellas"with the'side'wall.

. The sectionsofthedoor'bumpenas above ;The side walls .6fof-each'sec'tion-are'prefere ably-provided with the transverse apertures 21located below the ribs'20 and-when anuni-I her of adjacent parallel door bumpers are used, as shown in Figure 2 particularly, these door bumpers may be connected to each other by means of the rod 22 and the nuts 23 at opposite ends of the rod and spaced by means of the sleeves 24; located between the side walls of adjacent door bumpers, this arrangement providing for increasing the stability of each door bumper.

In the modification shown in Figure 6, the door bumper is secured to a different I-beam rail 25 and instead of the sides of the projections engaging the head and base of the I-beam rail, the faces 26 of the projections engage the web of the I-beam rail.

What I claim as my invention is:

1. A door bumper having cooperating sections, each with spaced anchoring and cushion receiving portions, and means for clamping said sections together and upon an anchoring member.

2. A door bumper having cooperating sections with opposite parts for engaging between the head and base of an anchoring member on opposite sides thereof, and cavity forming portions for receiving a cushion and means for clamping said sections together and to the anchoring member.

3. A door bumper having cooperating sections, each section having a body formed with a projection for engaging between the head and base of an anchoring member at one side thereof and with an arcuate portion, and a reinforcing web extending from said arcuate portion and merging into said body adjacent to but spaced from said projection to form therewith a recess for receiving one side of the head of the anchoring member, said pro jections and arcuate portions being respectively opposite each other, and means for clamping said sections together and to the anchoring member.

4. The combination with an I-beam anchoring member, of a door bumper secured thereto having cooperating sections, each section having a body with a side wall formed with a projection for engaging between the head and base of said I-beam anchoring menr her at one side thereof and with an arcuate portion and a back wall, and a reinforcing web extending transversely from said back wall, said projections and'arcuate portions being respectively opposite each other, a cushion between said arcuate portions, and means adjacent to said projections and arcuate portions for clamping said sections together and to said I-beam anchoring memher.

5. The combination with spaced anchoring members, of door bumpers secured to said anchoring members, each door bumper having cooperating sections with anchoring portions at one end and cushion receiving portions at the other end and means for clamp ing said sections together, and means for se curing said door bumpers relative to each other including a rod extending through the sections thereof, and spacers between the adjacent sections of adjacent bumpers.

6. A door bumper having cooperating sections, each with spaced anchoring and cushion receiving portions and a transversely ex tending reinforcing web adjacent said anchoring portion, and means for clamping said sections together, and upon an anchoring member.

7. A door bumper having cooperating sections, each with spaced anchoring and cushion rcceiving portions and a pair of spaced transversely extending reinforcing webs adj acent said anchoring portion, and means for clamping said sections together and upon an anchoring member.

8. A door bumper having cooperating sections, each with spaced anchoring and cushion receiving portions, of means for clamping said sections together upon an anchoring member, and cooperating means upon said sections for limiting movement of the sections toward each other.

9. A door bumper having cooperating sections, each section having a body provided with spaced anchoring and cushion receiving portions, each of said sections having a vertical front edge portion and a rear edge inclined upwardly and inwardly toward the front edge, and means for clamping said sec tions together upon an anchoring member.

10. A door bumper having cooperating sections, each having a body provided with spaced anchoring and cushion receiving portions and having a vertical front wall and a rear wall inclined upwardly and inwardly relative to said front wall, and means for clamping said sections together upon an anchoring member.

In testimony whereof I afiix my signature.
